    Sandbook 1.0.3 is a big stability and quality update. NEW • Prepare a chapter's audio ahead of time and keep listening with the screen locked. Shows progress and time remaining. • Share to Sandbook: send EPUB, PDF, TXT, RTF or selected text from any app. • Shortcuts: "Open Sandbook" and "Add Text to Sandbook". • RTF import. • Save typed, pasted or web text to your library. • Search chapters, jump to a page, drag to any position. • PDF table of contents when the file has one. • Optional Keep Screen Awake while reading. • Haptic feedback (can be turned off in Settings). • VoiceOver labels, Dynamic Type and Reduce Motion support. IMPROVED • PDFs no longer pause at every line break; hyphenated words are read as one word. • Large EPUBs open faster and use far less memory. • Pasted text reads every paragraph; no skipped or repeated sentences. • Pause and resume no longer skip sentences; changing chapter or voice no longer overlaps audio. • Importing a file with the same name no longer overwrites the old one. A damaged library index is repaired automatically. • An EPUB with one unreadable chapter now opens; playback continues if a single sentence cannot be voiced. • Web pages load faster and in the right order. • Audio export uses much less memory. • Sandbook no longer silences other apps' audio while paused in the background. • Your reading progress carries over from the previous version. Requires iOS 18.2 or later.
